Get the certificate expiration date of an application using codesign on mac?

Question

I'm trying to retrieve the certificate expiration date an application using the codesign command line tool, but I cannot seem to find the date that the certificate will expire. Any ideas?

Answer 1

Use codesign to extract the certificates to the current directory:

codesign --display --extract-certificates /Applications/Example.app

You can then use Quick Look to view them:

qlmanage -c public.x509-certificate -p codesign*
